  • a load distribution changing section which changes a ground load distribution between the front and rear wheels during driving of the vehicle;

    a slip suppressing condition determiner section which determines whether or not a suppressing condition used to suppress a slip of one of the front and rear wheels is met, during driving of the vehicle;

    a load distribution control section which controls the load distribution changing section to make the ground load of the one of the front and rear wheels greater, when the slip suppressing condition determiner section determines that the suppressing condition is met, than when the slip suppressing condition determiner section determines that the suppressing condition is not met; and

    buffer devices provided to correspond to the front and rear wheels, respectively, whereinthe load distribution changing section is an attitude changing section which changes an attitude of the vehicle around a pitching axis during driving of the vehicle;

    the load distribution control section controls the attitude changing section to change the attitude of the vehicle in a direction to increase the ground load of the one of the front and rear wheels; and

    the attitude changing section changes characteristics of the buffer devices to change the attitude of the vehicle.
